Going crazy trying to figure out my A/C problem..recently did a jdm swap but before that A/C was running good...after job was complete turned on A/C and when clutch engages loud knocking can be heard from compressor. Decided to just replace with another used one and ill be dam same noise. Well i went ahead and bought a new compressor installed it and getting it charged today. If it still makes that knock im gonna go crazy. Engine runs great, A/C gets cold but knocks like hell. Everything is tight so it's not just a raddle. Suggestions if new compressor don't fix the problem??
